* feat: let the backend, consumer and tracking service fetch their own MaxMind databases from GEODB_URL and TRACKING_SCANNER_ASN_DB_URL, reading the archive shape from the content so a permalink tar.gz, a gzipped mmdb and a bare mmdb all work, never replacing a file already at the path, opening the bytes before installing them so a licence-key error page cannot become the database forever, skipping the AppleDouble sidecars a macOS tar writes ahead of the real file, and treating both URLs as secrets because the permalink carries the licence key
* feat: drop the trailing blank line cargo fmt --check rejects at the end of tracking/src/asndb.rs
* feat: stream the downloaded ASN archive instead of decompressing it whole, sizing each buffer from the gzip footer and the tar header so the member is allocated exactly once, which drops the peak of unwrapping a permalink tar.gz from 38 MB to 11.9 MB, essentially the database itself
* feat: stop the MaxMind licence key reaching the logs through net/http's and reqwest's own error text, which both print the URL they were given and so defeated the redaction beside them, drop userinfo as well as the query when redacting, refuse plain http for a URL carrying a credential and refuse an https-to-http redirect, and apply the size cap to the decoded database rather than the compressed transfer so a gzip bomb cannot fill the disk
* feat: strip basic-auth userinfo as well as the query when the tracking service redacts its database URL, parsing it rather than cutting at the first question mark so where a credential sits is the URL library's problem and not a guess
* feat: shorten every recipient unsubscribe link from a 96-character signed token to a 22-character stored ticket carrying 128 bits from crypto/rand, minted once per recipient per campaign and reused by every step, so the address the text/plain half of a cold email prints in full fits on one line and cannot be guessed, keeping the signed form working for links already in inboxes and as the fallback when the store cannot be written, and answering a failed lookup with a retryable 'try again shortly' instead of telling the recipient their opt-out is invalid (issue #498)
* fix: restore the disabled-signer guard in URLOn, which factoring the URL builder moved behind a token mint that dereferences the signing key, so a nil or origin-less signer returns the empty string every caller reads as 'no link can be minted' instead of panicking (PR #525 review)
* feat: excuse one named account from the emailed login code, so a vendor reviewer who cannot read this instance's mail can sign in without turning codes off for everyone, with the reason recorded beside it and every run of warmblyctl status naming the accounts that hold one
* feat: create and manage tester accounts from the admin panel, so letting a reviewer in is a form rather than a shell, with the password shown once and every live exemption listed on one page because forgetting one is the way this goes wrong
* fix: give tester management its own permission bit rather than borrowing ban_users, create the account and its exemption in one transaction so no invisible orphan survives a failure, require an accountable operator on the CLI grant, stop a halted row scan reading as the whole exempt list, and show a failed query as an error instead of as no testers
* chore: re-run CI after the aggregator tripped on a cancelled job from the branch update, with every underlying job green
* chore: retrigger CI, the previous run sat queued indefinitely while other branches ran
* feat: roll back a half-created tester when its workspace step fails and backfill the manage-testers bit onto admins already holding every other permission, so the address is not left taken by an unusable account and the new routes are not 403 for the existing admin
* feat: make the 000151 manage-testers backfill one-way, because clearing bit 22 on the way down would also revoke it from an admin granted it explicitly afterwards and the up migration would not restore that
* feat: add operator-granted plans so a workspace can be paid without Stripe, surfaced in the admin panel as a badge, a filter and a card carrying who granted it and why, because the only alternative was writing a fake stripe subscription id into the database
* fix: hold a granted plan beside the paid one rather than over it so a Stripe workspace returns to the plan it pays for when the grant ends, route entitlement lookups through EffectivePlanID, separate a repository failure from an unknown plan, end a grant at local end of day, and drop an index that served no query
* feat: fix the six defects reported in issue #439 by mapping the IMAP UNAVAILABLE, INUSE and NONEXISTENT response codes to retry-level errors instead of a critical reconnect prompt, synthesising a stable no-msgid key so one message with no Message-ID header can no longer 400 the internal map endpoint and wedge every later sync pass with its cursors held, adding mailhtml.FromText and HasContent so an API or agent-created step with a plain body stops shipping the composer's empty div placeholder as its text/html part (derived on create and plain-only update, exposed as body_html on update_campaign_step, dropped at send and preview time, and refused at campaign start with empty_step_body), honouring sender_strategy='explicit' in ResolveCampaignSenderPool and ValidateCampaignReady so an emptied explicit pool parks the campaign instead of widening it to every mailbox in the workspace, making the paused_no_accounts auto-pause loud with an error log line, an error-level activity-feed entry and an org-scoped CAMPAIGN_PAUSED realtime pulse, gating the admin sign-in's Turnstile widget on GET /v1/auth/config so a self-host with CAPTCHA_PROVIDER=none is not locked out, and parsing NATS_URL down to its host:port so a credentialed bus URL no longer reports NATS down
* feat: act on the self-review of the issue #439 fixes by dropping the campaign wizard's own escapeHtml body_html builder, which entity-escaped the quotes in a conditional and made the template fail to parse at send time, and letting the backend's FromText render that part instead so wizard-written steps also get their bare URLs linked for click tracking, correcting the docs and openapi description that claimed an explicit sender pool never falls back when it still unions its tags as migration 000013 designed, extracting the duplicated blank-HTML-part guard into dropBlankHTMLPart shared by the send path and the preview, and recording why the no-msgid key keeps the folder name despite a RENAME changing it
* feat: address the CodeRabbit review on the issue #439 fixes by holding the admin sign-in's Turnstile widget unmounted until /v1/auth/config resolves so an instance with no route to Cloudflare cannot raise a widget error on a screen nobody submitted, failing StartCampaign closed when the sequence read errors rather than skipping both the malformed-template and empty-body refusals, giving TCPCheck the default port its protocol assumes so a portless NATS_URL is no longer reported down, leaving a URL that carries a merge field unanchored because the send path renders bodies with text/template and a quoted contact value would break out of the href, and correcting the sequences guide and the Campaign and CampaignUpdate openapi descriptions that named the wrong tag field
